    After World War II, the United States Air Force began developing a new weapon based on two existing ones: the V-2 rocket from Germany (with the help of a bloke named Werner von Braun), and the most terrible of all weapons, the nuclear bomb. The fusion of these two techologies was a simple idea, really: make a missile that could be guided to a target, and strap a nuke on the front.

    The crew entrance to Titan 725B, in the middle of nowhere, Colorado.

    What they came up with around 1955 was a twofold program. The SM-65 Atlas missile, which was lighter (its skin was no thicker than a US dime or UK 5p coin) and had less payload, and the appropriately named (if confusingly designated) HGM-25A Titan I missile. The Titan was built to be the Atlas' big brother. Bigger warhead, more range, hardened shelters (ie: underground silos).

    Layout of a typical Titan I complex. The silos were built to a cartoonishly big, evil-villain-hideout scale, with three silos and over a mile of connecting tunnels. (USAF)

    Each had a two stage liquid fuelled rocket with a range of 5,500 nautical miles (10,200 km); enough to get to the heart of Mother Russia. The propellants, cryogenic liquid oxygen and RP-1 (which is basically super-refined kerosene), were tough to handle, since they ignited on contact, but packed a wallop. The first test facility at Vandenburg AFB was destroyed when its missile was lowered into its silo too quickly - rupturing its skin and allowing the propellants to mix. The result was a blast which threw the silo cap hundreds of feet into the air - in pieces. Ouch.

    These missiles were deployed for the first time to silos at Lowry Air Force Base in Colorado in early 1960. Through the Cuban Missile Crisis, the Titans at Lowry stood on launch alert 24 hours a day - ready to send the 4 megatons of apocalyptic fire attached to each missile straight to anywhere in the world.

    After they were closed down in 1965 - that's right kids, five years later - the land was sold to various farmers who did some salvage work, usually taking copper piping and the steel plate floors from their silos. In this case, Farmer Bob dug up one of the giant diesel tanks that held fuel for the complex's generators. The resulting giant hole in the ground gave us an access point that is found in no other Titan site - a maintenance corridor to the second floor of the power dome, a giant 60-foot-tall room that held the generators for the complex.

    One warm May night, we ventured out into the moonlit Eastern plains of Colorado to explore this relic of the Cold War. The team that night consisted of myself, tunnelbug from California, secretdestroyers from Pittsburgh, and lexiphoto and orogeny from Denver. We parked our jeep a mile from the site and began the long walk back in.

    After finding our PoE, we emerged from the maintenance corridor and descended the steep stairway from the second level to the first of the powerhouse. Condensation drops clung to every surface, giving off an unearthly shimmer wherever the light from our headlamps touched them. The scale was immense. We stood in a room 60 feet high by 160 feet across, 40 feet underground in the middle of Farmer Bob's field.

    The 60-foot-high powerhouse of complex 725B. The ring around the top of the dome held a gantry crane used to move heavy machinery around in the limited space.

    The complex smelled of all sorts of nastiness. These silos were laden with PCBs, asbestos, airbourne lead, diesel, and all manner of chemical solvents. Our respirators were quickly donned, and added yet one more layer of unearthliness to the expedition. We were visitors in a very alien place, one which few are privileged enough to see, and a place that one held the power to end the world. Literally.

    These blast doors still moved without a squeak after 65 years underground.

    The tunnels were damp, but passable. The steel plate floors of the complex had long since been scrapped, so we were reduced to walking on the dirt of the tunnel floor. Tunnel junctions were a different story, as they were dug deeper to accommodate the various fuel and electrical lines. 65 years later, they had become moats, and necessitated beam walking to conquer them.

    The silos themselves loomed ahead. 160 feet from top to bottom, they originally held a complex latticework of steel that supported the giant rocket within it. The Titans did not burst from their silos on a pillar of flame like later ICBMs. The missiles were fuelled in their silos, and huge hydraulic rams would move the immense reinforced concrete doors covering the silo. After the doors were opened, the missiles would be hoisted up on a massive elevator attached to the cribbing, and launched. The whole process took 15 minutes for the first missile, and 7 minutes each for the last two. Only one could be armed and fired at a time. This lengthy procedure was one reason they went obsolete so quickly, the other being the liquid fuel. Liquid oxygen had to be kept at cryogenic temperatures requiring a lot of specialized equipment, and could not be stored in the missiles. By the time the Titans went on line, the next generation of solid-fuel ICBMs were already being designed. The Titan Is would soon be obsolete, replaced by the Titan IIs, which remained in the USAF arsenal until 1987.

    What once held an unbelievable destructive force was now slowly filling with water. During the rainy season, or after the spring snowmelt, some of the silos fill almost to the tunnel level with water, then they drain through the myriad cracks in the concrete walls. Some enterprising silo owners have converted these to indoor SCUBA tanks, but this one was now a watery graveyard for whatever animal was unlucky enough to tumble into the darkness. We stood 40 feet under the surface, with 120 feet worth of tangled metal and water below. It was an awe-inspiring experience knowing that this place once held such a terrible power. Each Titan I missile carried a 4 megaton thermonuclear warhead - more than enough to turn Moscow or St. Petersburg into a glowing, radioactive mass. The Little Boy bomb that leveled Hiroshima was a mere firecracker at 15 kilotons. 1 megaton of explosive equivalent, when converted to kilowatt-hours, produces enough energy to power the average American house for 103,474 years. And this complex housed not one, but three of these terrible devices. Walking with a big stick indeed.

    The control center was our last stop, a two story structure similar in size to the power dome, but a bit smaller. Its panels and computers long since removed, the nerve center of the complex was now home to graffiti, dead snakes (okay, dead snake), and empty beer cans. What must have gone through the minds of the men charged with the duty of being ready to annihilate the world I can only imagine.

    these racks held launch control computers and telephone equipment.

    We emerged from the silo around 4am, exhausted and smelling like arse, but with a new respect for the ground beneath our feet. Now all we have to do is crack the other 4 Titan Is in Colorado. Stay tuned.
